I can't figure out if vaccines work or not.

Tough one.

Need Sherlock Holmes on this one.

[Databricks @databricks]

At #RSAC2026, Databricks co-founder and CEO @alighodsi described a shift in how attacks are happening.

AI agents now move in swarms, scan massive amounts of data, write code quickly, and only need a single success to compromise an organization. At the same time, teams are working with incomplete data, discarding signals, and trying to keep up inside overloaded SOC environments and siloed systems.

His view is that this dynamic changes the role of traditional approaches, and that AI will replace SIEM this year. https://t.co/aYxTYfOxDt

𝕏 has always been the best source of financial news for traders and investors. Billions of dollars are allocated every day based on what people read on Timeline.

Today we're launching our new Cashtags feature in the US and Canada on iPhone, bringing real-time financial data to X.

Here's how it works:

1. When you search for or post a cashtag (or contract address), X will automatically suggest matching stocks or crypto tokens, so you can select the exact asset you had in mind.

2. Anyone who taps a Cashtag will see posts mentioning it along with its price chart—without ever leaving X.

This ensures that you're always matched to the chatter for the right stock or token.

Cashtags are just the first step in our commitment to be the best destination for the finance and crypto community.

Google warns quantum computing could break crypto sooner than expected by reducing the resources needed to crack today’s encryption. Not a current threat - but a real future one. The takeaway: crypto isn’t broken, but the clock is ticking to go quantum-safe.

Many are wondering "what Google saw" that caused them to revise their post-quantum cryptography transition deadline to 2029 last week. It was this:

Novel environments, no precedents or plagiarism possible. Humans 100%, AI <1%.

[Christian Marquay @cmarquay]

AI isn’t your brain. It’s your exoskeleton.

It doesn’t replace what you know. It amplifies it.

Less time searching. More time building.
Less hesitation. More iteration.
Same you.
Just faster, sharper, and harder to stop.

Technical skills are 20% of the job... but you 100% have to have them to get most jobs in data.

Here are the other 80% of skills that actually matter once you get the job:
- Turning vague questions into clear problems you can actually solve
- Knowing when “good enough” is better than perfect
- Communicating insights in a way non-technical people understand
- Asking better questions than anyone else in the room
- Understanding the business behind the data
- Managing stakeholders (and their expectations)
- Prioritizing what actually matters vs. what’s just noise
- Being reliable and hitting deadlines consistently
- Documenting your work so others can use it
- Not overcomplicating things just to look smart

You still need the hard-skills (and they're important for getting a job), but in the real world they aren't 100% of what you need.

- Drafted a blog post
- Used an LLM to meticulously improve the argument over 4 hours.
- Wow, feeling great, it’s so convincing!
- Fun idea let’s ask it to argue the opposite.
- LLM demolishes the entire argument and convinces me that the opposite is in fact true.
- lol

The LLMs may elicit an opinion when asked but are extremely competent in arguing almost any direction. This is actually super useful as a tool for forming your own opinions, just make sure to ask different directions and be careful with the sycophancy.

Quantum computing won’t kill banks or Web3 - it will expose who’s ready.

Banks can upgrade quietly. Web3 must coordinate loudly.

The real risk? Data harvested today, decrypted tomorrow.

This isn’t hype. It’s a race against time.

[Bark @barkmeta]

Let me explain what just happened 👇

5 minutes before the President announced a halt to attacks on Iran… someone placed a $1.5 BILLION bet on stocks going up and dumped $192 million in oil.

5 minutes…

These trades were 4 to 6 times larger than anything else in the entire market. Whoever did this wasn’t guessing. You don’t risk $1.5 billion on a hunch.

There was zero public indication this announcement was coming. No leaks. No press. Nothing. The only people who knew were in the room when the decision was made.

Someone in that room picked up a phone.
And within minutes they made more money than most Americans will earn in a thousand lifetimes. In a single trade. On a war that cost you $4+ a gallon gas and $16 billion in tax dollars.

American citizens funded this war. Politicians are profiting from it.

This is not the first time. Every major announcement from this administration has had massive suspicious trades right before it dropped. Tariff reversals. Policy shifts. War decisions.

This is the most blatant insider trading operation in the history of American politics. It’s not even close. And it’s happening over and over in broad daylight.

You would go to federal prison for trading on a tip from your cousin. These people are front running war decisions with billion dollar bets and nobody will ever ask a single question.

Nobody will be investigated. Nobody will be charged. By tomorrow this will be buried under the next satisfying headline. Just like last time. And the time before that.

The game is rigged. And they’re not even trying to hide it anymore…
